[TASK] Rename QueryContextType::NONE to QueryContextType::UNRESTRICTED

This name change transports the intent of the query context better and
makes it more intuitive to use.

Instead of explicitly disabling all enable fields and the deleted flag
using the following code:

$queryBuilder->getQueryContext()
    ->setIgnoreEnableFields(true)
    ->setIncludeDeleted(true);

the more descriptive predefined context can be used:

$queryBuilder->getQueryContext()->setContext('unrestricted')
